: I read in an earlier post that someone punched some holes out of the rear deck and thought they had better bass response with the stock (non-HK) radio. Where are these holes? Will you see this from the outside of the car? I looked from the inside of the trunk at the rear deck and I do not see anything. In each far corner of the trunk/rear deck there is a speaker right? There seems to be some kind of insulation between these speakers and the inside of the trunk. What components do I not have due to the lack of the HK? Any clarification on this subject would greatly be appreciated. Thank You?
